This is an open source “starter” project conceived by Steve M0MOI with the objective of creating a wide ranging signal source which can be put together using off the shelf modules and only a small amount of soldering. This project is based around a cheap and readily available ADF4351 development board.<\/p>\n

It is requested that anyone adding to this project or improving features or functions also make their material open source to all club members.<\/p>\n

\"Startup<\/a>

Startup Screen<\/p><\/div>\n

The soldering is mainly confined to the use of a rotary encoder to navigate the menus.<\/p>\n

The whole device runs from a usb cable which also serves as a means to update and change the internal program (which is non-volatile). The device will run from 34Mhz to 4.4Ghz and has two outputs. One for a continuous rf output the other will output Morse identifiers including call sign(C\/S)\u00a0 and maidenhead locator (LOC).<\/p>\n

The other menu options are frequency (F) and output level (LVL).<\/p>\n\n\t\t
